Answer:
Cost of white washing = ¥284
Step-by-step explanation:
Given that:
Area of door = 2* 1 = 2m sq.
Area of wall = 4.5*3.6 = 16.2m sq.
As we have to white wash the wall so we will deduct the area of door from area of wall as follows:
Total area = Area of wall - Area of door
Total area = 16.2m sq - 2m sq
Total area = 14.2m sq.
As the cost of white washing is ¥20 per meter so total cost will be:
Cost of white washing = 14.2 * 20
Cost of white washing = ¥284
i hope it will help you!
